Please add the new vertical tabs to the old version with Windows 7 support (ESR)

Please add the new vertical tabs to the old version with Windows 7 support (ESR) - Some people still use old laptops running Windows 7.

Vertical tabs won't ever come to the 115 ESR release, as it is security-fix only (and the rare bug-fix).  No new features will get added.

Have a look in the Firefox Add-Ons site to see if you can get an extension to do the same thing:
